diagnosis-eval-demo-gatekeeper-closure Brief

Background

The Chat evidence pipeline already had Executor V2 structured output, deterministic Gatekeeper validation, Verifier claim checks, and Composer final rendering. The missing piece was an interview-ready acceptance story that made the anti-hallucination behavior easy to demonstrate and regress.

Goal

Close the next three interview-readiness gaps together:

• diagnosis eval fixture matrix
• stable demo data set
• Gatekeeper rule configuration and audit version

Scope

• Expand mvp/eval with matrix-oriented cases, fixtures, and baseline reports.
• Add stable demo request payloads and scenario documentation.
• Add a lightweight local Gatekeeper rule catalog with rule_set_version and rule metadata in gatekeeper_result.
• Update architecture, demo, and eval docs to describe the current implementation.

Non-goals

• No new public HTTP endpoint.
• No new database table.
• No Planner scope_contract.
• No Gatekeeper retry loop.
• No remote or dynamic rule execution engine.

OpenSpec

• Change: openspec/changes/diagnosis-eval-demo-gatekeeper-closure
• Interface impact: L2 internal contract change.
